Water Conservation and Management

Yes, it is correct. The network of pipes below the ground for carrying sewage forms the sewerage.

This is the correct answer as public parks or play grounds etc. in urban and rural areas are de facto accessible to all the people living there. Thus, these are community owned.

Caves are formed by the dissolution of limestone by groundwater, making them a feature of underground water action. Cirques are formed by glaciers, mushroom rocks by wind abrasion, and cliffs by various erosion processes - none involve underground water.

Sewerage is not the destination of treated water.

Disease is not a cause of scarcity of fresh water, because it does not affect the water level.

Water from dams is not a source of sewage.

Sewers are the network of pipes that carry wastewater away from buildings. An aquifer is an underground water reservoir, tanks store water, and sanitation is the broader concept of maintaining hygienic conditions - none refer specifically to the pipe network.

This is the correct option as drip system is not a traditional method of irrigation. It is a modern system of irrigation.

Yes, she is doing water conservation. Water conservation is the process of reusing to prevent water from being lost or wasted.

Yes, above all statements are true. So this is the right answer.

Tank irrigation is the dominant type of irrigation in Peninsular India due to the region's undulating terrain, hard rock surface, and historical tradition of building tanks (eris) for water storage. Particularly prevalent in Tamil Nadu, Karnataka, and Andhra Pradesh, tanks were developed centuries ago to harvest monsoon rainfall.

Operation Flood (1970-1996) was India's dairy development program aimed at increasing milk production through cooperatives. It made India the world's largest milk producer and created the National Dairy Development Board.

Ponds that dry up completely each year are often known as vernal pools.

Underground water finds its way to the surface through springs.

Water seeping down from the land surface adds to the ground water and is called recharge water. Ground water is recharged from rain water and snowmelt or from water that leaks through the bottom of some lakes and rivers. Ground water also can be recharged when water-supply systems (pipelines and canals) leak and when crops are irrigated with more water than the plants can use.
